Cloudera — Sandbox Deployment and Install Guide Link to heading

Getting stuck is never fun. Especially when you’re working really hard on finishing up a project that has this “deadline” monster staring at you constantly through the skylight. I was caught up in a similar situation, on a Friday night, while working on a project involving integration with Hortonworks Data Platform on Hortonworks Sandbox.

I was using its Docker version on an AWS Instance and due to certain reasons, which I will mention in a while, the script provided by Hortonworks was incapable to bring the necessary containers up. So, in this post, I have made a note of the steps that I took in order to resolve the issue and make the setup work.

You have to keep in mind that the setup has huge containers ( ~30GB ) and it needs to have at least 10GB of RAM to work properly. These are the prerequisites as mentioned by the Sandbox Deployment and Install Guide. I was using AWS Image: Docker Infrastructure Ubuntu 14.04, which comes with Ubuntu Version: 1.10.2 preinstalled. So, depending upon your Docker version, you may or may not get the errors that have been listed below.

The guide tells you to run the below command:

sh docker-deploy-{HDPversion}.sh
#In my case HDPVersion is 30 : docker-deploy-hdp30.sh

Depending upon your version of Linux, you may have to either run it as bash.

From this point onward, we may have different kinds of errors or no errors at all. I am putting the errors that I got and how I have resolved them.

The first message which popped up was:

+ docker run --privileged --name sandbox-hdp -h sandbox-hdp.hortonworks.com --network
flag provided but not defined: --network
See 'docker run --help'.

If you check docker documentation, it shows:

$ docker run --help | grep net  
  --net=default           Connect a container to a network
  --net-alias=[]          Add network-scoped alias for the container

Replace the flag from network to net in the script docker-deploy-hdp30.sh at line #40

docker run --privileged --name $name -h $hostname --net=cda --net-alias=$hostname -d "$registry/$name:$version"

The next error was:

+ docker exec -t sandbox-hdp sh -c 'rm -rf /var/run/postgresql/*; systemctl restart p
Error response from daemon: Container sandbox-hdp is not running

This could be due to the previous error so let’s ignore it for the time being. Following this was:

+ sandbox/proxy/proxy-deploy.sh
sandbox-proxy
flag provided but not defined: --network
See 'docker run --help'.

Upon looking into the script docker-deploy-hdp30.sh, at the last line, there is a call to another script, i.e. sandbox/proxy/proxy-deploy.sh. Open the file sandbox/proxy/proxy-deploy.sh and replace the network flag with net as shown below. Remember to open this file as sudo

docker run --name sandbox-proxy --net=cda \

Then run only the sandbox/proxy/proxy-deploy.sh script. Do not go back and run the docker-deploy-hdp30.sh file or else you will have to make the changes again, as it creates a new sandbox/proxy/proxy-deploy.sh file everytime. When I ran it, I got the error as :

docker: Error response from daemon: 
failed to create endpoint sandbox-proxy on network cda: Bind for 0.0.0.0:8000 failed: 
port is already allocated.

So, I changed the port from 8000 to 18000 and ran the script again and it solved my problem.

Now the HDP setup is ready and you can play with it.

$ docker ps | grep sandbox-hdp
f55b44e38022   hortonworks/sandbox-hdp:3.0.1  "/usr/sbin/init"   14 minutes ago   Up 14 minutes      22/tcp, 4200/tcp, 8080/tcp    sandbox-hdp
$docker exec -it f55b44e38022 bin/bash
[root@sandbox-hdp /]# hive

Thank you,

Cheers!!!
